Fractional Integration and Differentiation

Part of the Cornerstones book series (COR)


In this chapter we deal with “complex powers of the operator \(\frac{d}{{dx}},\)” a concept already found in the posthumous works of Riemann and elaborated by Marcel Riesz in the 1930s and 1940s. The relevant article [18] is lengthy, but with the help of a little distribution theory and complex analysis, all results can readily be proved.We will also deal with Riesz’s treatment of the wave operator \(\Box = \partial _t^2 -\triangle_{x}\) in arbitrary dimension; thus we will obtain, among other things, a fundamental solution of \(\Box.\)
